New digital platform streamlines spatial and geometric changes at the Hellenic Cadastre

Any boundary correction, land subdivision, parcel consolidation or geometric alteration requiring a new cadastral survey continued to rely on paper files, manual reviews and repeated visits to Cadastral Offices.

The consequences were well known to engineers, notaries, lawyers and investors alike: property transactions remaining pending for months, development projects unable to move forward, and real estate deals delayed until the verification of cadastral and geometric data had been completed.

The Hellenic Cadastre is now seeking to change this reality through its new Integrated Information System, financed under the Greece 2.0 Recovery and Resilience Plan, which was presented during the conference “The Hellenic Cadastre in the Digital Era.”

At the centre of the initiative is the new “Changes” application, through which applications for spatial and geometric modifications will be submitted entirely online. Property owners and their engineers will be able to file both the application and the required cadastral survey plans electronically, eliminating the need for physical documentation.

The reform could have a greater impact on the real estate market than initially appears. Today, a significant share of property transactions is delayed because a boundary correction, parcel consolidation or cadastral discrepancy must first be resolved. While these procedures remain pending, the associated investment is effectively put on hold.

The new system aims to reduce these delays through automated workflows. Cases will be assigned digitally to the competent engineers, while all parties involved will be able to monitor their progress electronically from submission through to completion. Adjacent property owners will also receive automatic notifications whenever a proposed modification affects their property rights and will be able to submit their observations online.

The initiative forms part of a broader effort to unify the Cadastre’s digital ecosystem. The multiple online portals currently in operation will be replaced by a single platform hosted on ktimatologio.gov.gr, while all information systems will operate within a unified cloud environment.

At the same time, a new national geospatial database based on the ArcGIS Parcel Fabric standard is being developed. The project is expected to significantly improve the accuracy and management of cadastral data by creating, for the first time, a single digital representation of property parcels across the country, replacing the current fragmented system of separate regional databases.

Certified engineers are also expected to play a key role by undertaking part of the review process for geometric modifications under the supervision of the Hellenic Cadastre. The measure is intended to ease the administrative burden on cadastral services and accelerate the processing of thousands of pending cases.

The reforms come at a time when the Hellenic Cadastre reports that it has now completed cadastral coverage for 99% of the country’s territory, integrated all former Mortgage Offices into its operations, and finalised the migration of its data to the government’s cloud infrastructure.

The progress of the Cadastre’s digital transformation programme was presented during the online conference “The Hellenic Cadastre in the Digital Era,” held on 8 July in cooperation with Vodafone.
